Machine Learning Engineering Manager – Marketplace

Machine Learning Engineering Manager – Marketplace

At Roblox, our Marketplace Search & Recommendation team powers the discovery of avatar content across the platform—from bodies, clothing, and accessories to fully styled outfits—spanning the Roblox app and immersive in-experience surfaces. We’re reimagining how discovery and personalization can unlock creativity and economic opportunity for millions of users and creators.

We’re looking for a Machine Learning Engineering Manager to lead a team of exceptional ML engineers tackling core challenges across ranking, retrieval, and multimodal content understanding. This includes everything from advancing deep learning models for search and recommendation, to developing systems that understand the textual and visual semantics of avatar content and drive long-term value for the Roblox economy.

You Will::

• Define and drive the technical roadmap for ML across Search, Recommendation, and Content Understanding.
• Lead the development of scalable, production-ready ML systems—from raw data to model deployment.
• Collaborate cross-functionally with product, design, and data science to build intelligent discovery experiences.
• Recruit, mentor, and grow a high-performing team of ML engineers.
• Establish engineering best practices to ensure system reliability, extensibility, and performance.
  
  

You Have:

• Leadership Experience: 3+ years managing ML engineers or scientists; 5+ years building ML systems at scale in search, recommender systems, or ads.
• Strong Technical Foundation: Degree in Computer Science, Engineering, Math, Physics, or a related field—or equivalent hands-on experience.
• Depth in ML: Proven track record shipping deep learning models across ranking, retrieval, NLP, computer vision, or multimodal pipelines. Experience using transformer architectures and LLMs in production systems is a strong plus.
• End-to-End Execution: You’ve built ML systems from data ingestion to serving in production.
• Strategic Thinking: You’re comfortable balancing near-term impact with long-term innovation.
• Team-first Mindset: A collaborative leader who thrives on mentoring and enabling others to succeed.
